Headlamp Aiming - Buick 2006 Lucerne Owner's Manual

Headlamp Aiming

The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been preset at
the factory and should need no further adjustment.
However, if the vehicle is damaged in an accident, the
aim of the headlamps may be affected and adjustment
may be necessary.
If oncoming vehicles flash their high beams at you, this
may mean the vertical aim of your headlamps needs
to be adjusted.
It is recommended that the vehicle is taken to your
dealer for service if the headlamps need to be adjusted.
It is possible however, to re-aim the headlamps as
described in the following procedure.
The vehicle should be properly prepared as follows:
•
The vehicle should be placed so the headlamps are
25 ft. (7.6 m) from a light colored wall or other flat
surface.
•
The vehicle must have all four tires on a level
surface which is level all the way to the wall or other
flat surface.
•
The vehicle should be placed so it is perpendicular
to the wall or other flat surface.
•
The vehicle should not have any snow, ice or
mud on it.
•
The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being
performed.
•
The vehicle should be normally loaded with a full
tank of fuel and one person or 160 lbs (75 kg)
sitting on the driver's seat.
•
Tires should be properly inflated.
•
The spare tire is in its proper location in the vehicle.
Headlamp aiming is done with the vehicle's low-beam
headlamps. The high-beam headlamps will be correctly
aimed if the low-beam headlamps are aimed properly.
